Look up Andreas Malm and the self admitted super cringe name Indians of the Concrete Jungle action that they did in Sweden in the 2000’s. It turns out you don’t need legal bans to do this, but can effectively ban specific models from city centers by continually letting out the air in their tires whenever they’re parked at night.
No one gets hurt, it doesn’t even damage the vehicles, but they have to tow them out, refill their tires and hopefully never come back.
None of these things are activism, with maybe a carve-out for writing your elected representatives depending on what political culture you are in.
What we’re asking is what kinds of activism can help mitigate the damage or change the trends of car use in urban areas?
